The results were published in the Journal of Economic Entomology.http://phys.org/news/2015-10-glyphosate-acetamiprid-toxicity-honey-bees.html
Ecology Tue, 13 Oct 2015 07:59:46 ESTnews363941971Lab test commonly used to assess water toxicityHyalella azteca are invertebrates that are widely used for sediment and water toxicity studies. Investigators have found that H. azteca collected from sites influenced by agricultural/urban runoff are as much as 2-times less sensitive to pyrethroid insecticides than lab-grown H. azteca. In contrast, the insecticide sensitivities of H. azteca collected from undeveloped sites beyond the influences of agricultural/urban runoff were similar to those of lab-grown populations.http://phys.org/news/2015-05-lab-commonly-toxicity.html
Ecology Mon, 04 May 2015 13:22:29 ESTnews349964542Researchers crack the genetic secret of mosquito resistance to DDT and ITNsResearchers from LSTM have found that a single genetic mutation causes resistance to DDT and pyrethroids (an insecticide class used in mosquito nets). With the continuing rise of resistance the research, published in the journal Genome Biology, is key as scientists say that this knowledge could help improve malaria control strategies.http://phys.org/news/2014-02-genetic-secret-mosquito-resistance-ddt.html

Their study on pyrethroid insecticides—used in more than 3,500 products—was part of the 246th National Meeting & Exposition of the American Chemical Society (ACS).http://phys.org/news/2013-09-sewage-treatment-widely-home-garden.html

This door, however, is closing, giving mosquitoes the upper hand.http://phys.org/news/2013-07-door-war-mosquito-borne-diseases.html

Ecology Wed, 01 Feb 2012 16:56:58 ESTnews247337809Bed bug insecticide resistance mechanisms identifiedBed bugs, largely absent in the U.S. since the 1950s, have returned with a hungry vengeance in the last decade in all 50 states. These insects have developed resistance to pyrethroids, one of the very few classes of insecticide used for their control. A research team at Virginia Tech has discovered some of the genetic mechanisms for the bed bug's resistance to two of the most popular pyrethroids -- deltamethrin and beta-cyfluthrin.http://phys.org/news/2011-10-bed-bug-insecticide-resistance-mechanisms.html
